Patient values in patient-provider communication about participation in early phase clinical cancer trials: a qualitative analysis before and after implementation of an online value clarification tool intervention.

BACKGROUND: Patients with advanced cancer who no longer have standard treatment options available may decide to participate in early phase clinical trials (i.e. experimental treatments with uncertain outcomes). Shared decision-making (SDM) models help to understand considerations that influence patients' decision. Discussion of patient values is essential to SDM, but such communication is often limited in this context and may require new interventions. The OnVaCT intervention, consisting of a preparatory online value clarification tool (OnVaCT) for patients and communication training for oncologists, was previously developed to support SDM. This study aimed to qualitatively explore associations between patient values that are discussed between patients and oncologists during consultations about potential participation in early phase clinical trials before and after implementation of the OnVaCT intervention. METHODS: This study is part of a prospective multicentre nonrandomized controlled clinical trial and had a between-subjects design: pre-intervention patients received usual care, while post-intervention patients additionally received the OnVaCT. Oncologists participated in the communication training between study phases. Patients' initial consultation on potential early phase clinical trial participation was recorded and transcribed verbatim. Applying a directed approach, two independent coders analysed the transcripts using an initial codebook based on previous studies. Steps of continuous evaluation and revision were repeated until data saturation was reached. RESULTS: Data saturation was reached after 32 patient-oncologist consultations (i.e. 17 pre-intervention and 15 post-intervention). The analysis revealed the values: hope, perseverance, quality or quantity of life, risk tolerance, trust in the healthcare system/professionals, autonomy, social adherence, altruism, corporeality, acceptance of one's fate, and humanity. Patients in the pre-intervention phase tended to express values briefly and spontaneously. Oncologists acknowledged the importance of patients' values, but generally only gave 'contrasting' examples of why some accept and others refuse to participate in trials. In the post-intervention phase, many oncologists referred to the OnVaCT and/or asked follow-up questions, while patients used longer phrases that combined multiple values, sometimes clearly indicating their weighing. CONCLUSIONS: While all values were recognized in both study phases, our results have highlighted the different communication patterns around patient values in SDM for potential early phase clinical trial participation before and after implementation of the OnVaCT intervention. This study therefore provides a first (qualitative) indication that the OnVaCT intervention may support patients and oncologists in discussing their values.

The effect of a palliative care pathway on medical interventions at the end of life: a pre-post-implementation study.

PURPOSE: Adequate integration of palliative care in oncological care can improve the quality of life in patients with advanced cancer. Whether such integration affects the use of diagnostic procedures and medical interventions has not been studied extensively. We investigated the effect of the implementation of a standardized palliative care pathway in a hospital on the use of diagnostic procedures, anticancer treatment, and other medical interventions in patients with incurable cancer at the end of their life. METHODS: In a pre- and post-intervention study, data were collected concerning adult patients with cancer who died between February 2014 and February 2015 (pre-PCP period) or between November 2015 and November 2016 (post-PCP period). We collected information on diagnostic procedures, anticancer treatments, and other medical interventions during the last 3 months of life. RESULTS: We included 424 patients in the pre-PCP period and 426 in the post-PCP period. No differences in percentage of laboratory tests (85% vs 85%, p = 0.795) and radiological procedures (85% vs 82%, p = 0.246) were found between both groups. The percentage of patients who received anticancer treatment or other medical interventions was lower in the post-PCP period (40% vs 22%, p < 0.001; and 42% vs 29%, p < 0.001, respectively). CONCLUSIONS: Implementation of a PCP resulted in fewer medical interventions, including anticancer treatments, in the last 3 months of life. Implementation of the PCP may have created awareness among physicians of patients' impending death, thereby supporting caregivers and patients to make appropriate decisions about medical treatment at the end of life.

Core values of patients with advanced cancer considering participation in an early-phase clinical trial: a qualitative study.

OBJECTIVE: This article identifies the core values that play a role in patients' decision-making process about participation in early-phase clinical cancer trials. METHODS: Face-to-face, semi-structured serial interviews (n = 22) were performed with thirteen patients with advanced cancer recruited in two Dutch specialized cancer centers. In a cyclic qualitative analysis process, open and axial coding of the interviews finally led to an overview of the values that are woven into patients' common language about cancer and clinical trials. RESULTS: Six core values were described, namely, acceptance creates room for reconsideration of values, reconciliation with one's fate, hope, autonomy, body preservation, and altruism. Previously found values in advanced cancer, such as acceptance, hope, autonomy, and altruism, were further qualified. Reconciliation with one's fate and body preservation were highlighted as new insights for early-phase clinical cancer trial literature. CONCLUSIONS: This article furthers the understanding of core values that play a role in the lives and decision-making of patients with advanced cancer who explore participation in early-phase clinical cancer trials. These values do not necessarily have to be compatible with one another, making tragic choices necessary. Understanding the role of core values can contribute to professional sensitivity regarding what motivates patients' emotions, thoughts, and decisions and help patients reflect on and give words to their values and preferences. It supports mutual understanding and dialog from which patients can make decisions according to their perspectives on a good life for themselves and their fellows in the context of participation in an early-phase clinical cancer trial.

When a dying patient is asked to participate in a double-blind, placebo-controlled clinical trial on symptom control: The decision-making process and experiences of relatives.

BACKGROUND: Placebo-controlled trials can provide evidence to inform end-of-life care, but it is contested whether asking dying patients to participate in such trials is morally justifiable. To investigate the experiences of these patients is even more complex. Therefore, proxy assessments by relatives can be a good alternative. AIM: To explore the experience of participating in a placebo-controlled trial at the end of life from the perspective of bereaved relatives. DESIGN: Mixed-method study, including questionnaires and interviews. SETTING/PARTICIPANTS: The SILENCE study was a randomized, double-blind, placebo-controlled trial on the efficacy of scopolamine butylbromide to prevent death rattle. The study was performed in six inpatient hospice facilities. Patients were asked to participate at admission in the hospice. Three months after the death of the patient, bereaved relatives were invited to fill in a questionnaire and to participate in an interview. One hundred four questionnaires were completed and 17 relatives were interviewed. RESULTS: Fourteen percent of the relatives participating in the questionnaire study considered the participation of their loved one in research a bit burdensome and 10% considered it a bit stressful. Seventeen percent thought that it was a bit burdensome for the patient. Eighty-three percent considered participation in this type of research (very) valuable. The in-depth interviews showed that patients and relatives jointly decided about participation in this double-blind placebo-controlled medication trial. Relatives generally respected and felt proud about patients' decision to participate. CONCLUSION: The large majority of bereaved relatives experienced the participation of their dying love one in this RCT as acceptable and valuable.

The development of the ADO-SQ model to predict 1-year mortality in patients with COPD.

BACKGROUND: Goals of end-of-life care must be adapted to the needs of patients with chronic obstructive pulmonary disease (COPD) who are in the last phase of life. However, identification of those patients is limited by moderate performances of existing prognostic models and by limited validation of the often-recommended surprise question. AIM: To develop a clinical prediction model to predict 1-year mortality in patients with COPD. DESIGN: Prospective study using logistic regression to develop a model in two steps: (1) external validation of the ADO, BODEX, or CODEX models (A = age; B = body mass index; C = comorbidity; D = dyspnea; EX = exacerbations; O = airflow obstruction); (2) updating of best performing model and extending it with the surprise question. Discriminative performance of the new model was assessed using internal-external validation and measured with area under the curve (AUC). A nomogram and web application were developed. SETTINGS/PARTICIPANTS: Patients with COPD from five hospitals (September-November 2017). RESULTS: Of the 358 included patients (median age 69.5 years, 50% male), 63 (17%) died within a year. The ADO index (AUC 0.73) had the best discriminative ability compared to the BODEX (AUC 0.71) or CODEX (AUC 0.68), and was extended with the surprise question. The resulting ADO-surprise question (SQ) model had an AUC of 0.79. CONCLUSION: The ADO-SQ model offers improved discriminative performance for predicting 1-year mortality compared to the surprise question, ADO, BODEX, or CODEX. A user-friendly nomogram and web application (https://dnieboer.shinyapps.io/copd) were developed. Further external validation of the ADO-SQ in patient groups is needed.

Predictors of mortality in chronic obstructive pulmonary disease: a systematic review and meta-analysis.

BACKGROUND: Better insight in patients' prognosis can help physicians to timely initiate advance care planning (ACP) discussions with patients with chronic obstructive pulmonary disease (COPD). We aimed to identify predictors of mortality. METHODS: We systematically searched databases Embase, PubMed, MEDLINE, Web of Science, and Cochrane Central in April 2020. Papers reporting on predictors or prognostic models for mortality at 3 months and up to 24 months were assessed on risk-of-bias. We performed a meta-analysis with a fixed or random-effects model, and evaluated the discriminative ability of multivariable prognostic models. RESULTS: We included 42 studies (49-418,251 patients); 18 studies were included in the meta-analysis. Significant predictors of mortality within 3-24 months in the random-effects model were: previous hospitalization for acute exacerbation (hazard ratio [HR] 1.97; 95% confidence interval [CI] 1.32-2.95), hospital readmission within 30 days (HR 5.01; 95% CI 2.16-11.63), cardiovascular comorbidity (HR 1.89; 95% CI 1.25-2.87), age (HR 1.48; 95% CI 1.38-1.59), male sex (HR 1.68; 95% CI 1.38-1.59), and long-term oxygen therapy (HR 1.74; 95% CI 1.10-2.73). Nineteen previously developed multicomponent prognostic models, as examined in 11 studies, mostly had moderate discriminate ability. CONCLUSION: Identified predictors of mortality may aid physicians in selecting COPD patients who may benefit from ACP. However, better discriminative ability of prognostic models or development of a new prognostic model is needed for further large-scale implementation.

Hospitalisations of patients with cancer in the last stage of life. Reason to improve advance care planning?

OBJECTIVE: The aim of this study is to examine why patients are hospitalised in the last stage of life. METHODS: Our study was conducted in a large Dutch teaching hospital. We conducted a retrospective chart review of patients aged ≥18 years who died of cancer either during hospitalisation or after discharge to receive terminal care outside the hospital. We collected data about the characteristics of these hospitalisations and indicators of advance care planning. RESULTS: Of the 264 deceased patients, 56% had died in the hospital and 44% after hospital discharge. Of all patients, 80% had been admitted to the hospital because of symptom distress. Dyspnoea (39%) and pain (33%) were the most common symptoms. Most patients underwent diagnostic procedures (laboratory tests [97%] and radiology tests [91%]) and received medical treatment (analgesics [71%] and antibiotics [55%]) during their hospitalisation. A 'Do-Not-Resuscitate' code had been recorded before admission in 42% of the patients and in an additional 52% during admission. CONCLUSION: Our study shows that patients with cancer in the last stage of life were mainly admitted to the hospital because of symptom distress. Some hospitalisations and in-hospitals deaths may be avoided by more timely recognition of patients' impending death and start of advance care planning.

Challenges in self-management of persons living with advanced cancer: An exploratory, in-depth interview study.

OBJECTIVE: To obtain insight in self-management challenges of persons with advanced cancer and factors that influence their self-management. METHODS: Exploratory study among persons with advanced cancer. We conducted in-depth interviews and performed an inductive thematic analysis, using open, axial and selective coding. RESULTS: We interviewed 33 persons with advanced cancer. Four self-management challenges were identified: (1) Dealing with physical and psychological symptoms and problems. (2) Navigating the illness trajectory, including management of clinical appointments and treatment regimens, end-of-life planning life and 'maintaining normality'. (3) Managing relations with healthcare professionals, including contributing experiential knowledge to medical decision-making. (4) Navigating changes in the social environment. Some participants responded proactively to these challenges, for example, by actively searching for information to obtain an extensive understanding of their illness and (re)scheduling medical appointments for a better fit in their agenda. Self-management strategies seemed to be influenced by patients' personality, life history, moment in the illness trajectory and the social environment. CONCLUSION: Self-management challenges of persons with advanced cancer are based largely outside the professional care setting. Self-management strategies in response to these challenges are typically aimed at maintaining a normal life. Self-management support should be tailored to patients' needs and part of trustful partnerships with patients and relatives.

Opportunities and challenges for advance care planning in strongly religious family-centric societies: a Focus group study of Indonesian cancer-care professionals.

BACKGROUND: Most studies on advance care planning in Asia originate in high-income Asian countries. Indonesia is a middle-income Asian country characterized by its religious devoutness and strong family ties. This study aims to explore the perspectives and experiences of Indonesian healthcare professionals on advance care planning for cancer patients. METHODS: Focus-group discussions were conducted in July and August 2019 and were analysed using thematic content analysis enhanced by dual coding and exploration of divergent views. Purposive sampling of physicians and nurses actively engaged in cancer care in a national cancer centre and a national general hospital. RESULTS: We included 16 physicians and 16 nurses. These participants were open to the idea of advance care planning. We further identified four aspects of this planning that the participants considered to be important: 1) the family's role in medical decision-making; 2) sensitivity to communication norms; 3) patients' and families' religious beliefs regarding the control and sanctity of life; and 4) the availability of a support system for advance care planning (healthcare professionals' education and training, public education, resource allocation, and formal regulation). Participants believed that, although family hierarchical structure and certain religious beliefs may complicate patients' engagement in advance care planning, a considerate approach to involving family and patients' religious perspectives in advance care planning may actually facilitate their engagement in it. CONCLUSION: Indonesian healthcare professionals believed that, for culturally congruent advance care planning in Indonesia, it was essential to respect the cultural aspects of collectivism, communication norms, and patients' religious beliefs.

Advance care planning for patients with cancer and family caregivers in Indonesia: a qualitative study.

BACKGROUND: Individuals' willingness to engage in advance care planning is influenced by factors such as culture and religious beliefs. While most studies on advance care planning in Asia have been performed in high-income countries, Indonesia is a lower-middle-income country, with a majority of strongly collectivist and religiously devout inhabitants. We studied the perspectives of Indonesian patients with cancer and family caregivers regarding advance care planning by first exploring their experiences with medical information-disclosure, decision-making, and advance care planning and how these experiences influence their perspectives on advance care planning. METHODS: We conducted semi-structured interviews among 16 patients with cancer and 15 family caregivers in a national cancer center in Jakarta and a tertiary academic general hospital in Yogyakarta. We performed an inductive thematic analysis using open, axial, and selective coding. The rigor of the study was enhanced by reflective journaling, dual coding, and investigator triangulation. RESULTS: Twenty-six of 31 participants were younger than 60 years old, 20 were Muslim and Javanese, and 17 were college or university graduates. Four major themes emerged as important in advance care planning: (1) participants' perceptions on the importance or harmfulness of cancer-related information, (2) the importance of communicating bad news sensitively (through empathetic, implicit, and mediated communication), (3) participants' motives for participating in medical decision-making (decision-making seen as patients' right or responsibility, or patients' state of dependency on others), and (4) the complexities of future planning (e.g., due to its irrelevance to participants' religious beliefs and/or their difficulties in seeing the relevance of future planning). CONCLUSIONS: Culturally sensitive approaches to advance care planning in Indonesia should address the importance of facilitating open communication between patients and their families, and the various perspectives on information provision, bad news communication, and decision-making. Advance care planning should focus on the exploration of patients' values, rather than drafting treatment plans in advance.

Asian patients' perspectives on advance care planning: A mixed-method systematic review and conceptual framework.

BACKGROUND: Asian healthcare professionals hold that patients' families play an essential role in advance care planning. AIM: To systematically synthesize evidence regarding Asian patients' perspectives on advance care planning and their underlying motives. DESIGN: Mixed-method systematic review and the development of a conceptual framework (PROSPERO: CRD42018099980). DATA SOURCES: EMBASE, MEDLINE, Web of Science, and Google Scholar were searched for studies published until July 27, 2020. We included studies concerning seriously-ill Asian patients' perspectives on advance care planning or their underlying motives for engaging or not engaging in it. RESULTS: Thirty-six articles were included; 22 were quantitative and 27 were from high-income countries. Thirty-nine to ninety percent of Asian patients were willing to engage in advance care planning. Our framework highlighted that this willingness was influenced not only by their knowledge of their disease and of advance care planning, but also by their beliefs regarding: (1) its consequences; (2) whether its concept was in accordance with their faith and their families' or physicians' wishes; and (3) the presence of its barriers. Essential considerations of patients' engagement were their preferences: (1) for being actively engaged or, alternatively, for delegating autonomy to others; (2) the timing, and (3) whether or not the conversations would be documented. CONCLUSION: The essential first step to engaging patients in advance care planning is to educate them on it and on their diseases. Asian patients' various beliefs about advance care planning should be accommodated, especially their preferences regarding their role in it, its timing, and its documentation.

The Value of the Surprise Question to Predict One-Year Mortality in Idiopathic Pulmonary Fibrosis: A Prospective Cohort Study.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a progressive fatal disease with a heterogeneous disease course. Timely initiation of palliative care is often lacking. The surprise question "Would you be surprised if this patient died within the next year?" is increasingly used as a clinical prognostic tool in chronic diseases but has never been evaluated in IPF. OBJECTIVE: We aimed to evaluate the predictive value of the surprise question for 1-year mortality in IPF. METHODS: In this prospective cohort study, clinicians answered the surprise question for each included patient. Clinical parameters and mortality data were collected. The sensitivity, specificity, accuracy, negative, and positive predictive value of the surprise question with regard to 1-year mortality were calculated. Multivariable logistic regression analysis was performed to evaluate which factors were associated with mortality. In addition, discriminative performance of the surprise question was assessed using the C-statistic. RESULTS: In total, 140 patients were included. One-year all-cause mortality was 20% (n = 28). Clinicians identified patients with a survival of <1 year with a sensitivity of 68%, a specificity of 82%, an accuracy of 79%, a positive predictive value of 49%, and a negative predictive value of 91%. The surprise question significantly predicted 1-year mortality in a multivariable model (OR 3.69; 95% CI 1.24-11.02; p = 0.019). The C-statistic of the surprise question to predict mortality was 0.75 (95% CI 0.66-0.85). CONCLUSIONS: The answer on the surprise question can accurately predict 1-year mortality in IPF. Hence, this simple tool may enable timely focus on palliative care for patients with IPF.

Effect of Prophylactic Subcutaneous Scopolamine Butylbromide on Death Rattle in Patients at the End of Life: The SILENCE Randomized Clinical Trial.

Importance: Death rattle, defined as noisy breathing caused by the presence of mucus in the respiratory tract, is relatively common among dying patients. Although clinical guidelines recommend anticholinergic drugs to reduce the death rattle after nonpharmacological measures fail, evidence regarding their efficacy is lacking. Given that anticholinergics only decrease mucus production, it is unknown whether prophylactic application may be more appropriate. Objective: To determine whether administration of prophylactic scopolamine butylbromide reduces the death rattle. Design, Setting, and Participants: A multicenter, randomized, double-blind, placebo-controlled trial was performed in 6 hospices in the Netherlands. Patients with a life expectancy of 3 or more days who were admitted to the participating hospices were asked to give advance informed consent from April 10, 2017, through December 31, 2019. When the dying phase was recognized, patients fulfilling the eligibility criteria were randomized. Of the 229 patients who provided advance informed consent, 162 were ultimately randomized. The date of final follow-up was January 31, 2020. Interventions: Administration of subcutaneous scopolamine butylbromide, 20 mg four times a day (n = 79), or placebo (n = 78). Main Outcomes and Measures: The primary outcome was the occurrence of a grade 2 or higher death rattle as defined by Back (range, 0-3; 0, no rattle; 3, rattle audible standing in the door opening) measured at 2 consecutive time points with a 4-hour interval. Secondary outcomes included the time between recognizing the dying phase and the onset of a death rattle and anticholinergic adverse events. Results: Among 162 patients who were randomized, 157 patients (97%; median age, 76 years [IQR, 66-84 years]; 56% women) were included in the primary analyses. A death rattle occurred in 10 patients (13%) in the scopolamine group compared with 21 patients (27%) in the placebo group (difference, 14%; 95% CI, 2%-27%, P = .02). Regarding secondary outcomes, an analysis of the time to death rattle yielded a subdistribution hazard ratio (HR) of 0.44 (95% CI, 0.20-0.92; P = .03; cumulative incidence at 48 hours: 8% in the scopolamine group vs 17% in the placebo group). In the scopolamine vs placebo groups, restlessness occurred in 22 of 79 patients (28%) vs 18 of 78 (23%), dry mouth in 8 of 79 (10%) vs 12 of 78 (15%), and urinary retention in 6 of 26 (23%) vs 3 of 18 (17%), respectively. Conclusions and Relevance: Among patients near the end of life, prophylactic subcutaneous scopolamine butylbromide, compared with placebo, significantly reduced the occurrence of the death rattle.

Realizing better doctor-patient dialogue about choices in palliative care and early phase clinical trial participation: towards an online value clarification tool (OnVaCT).

BACKGROUND: Patients with advanced cancer for whom standard systemic treatment is no longer available may be offered participation in early phase clinical trials. In the decision making process, both medical-technical information and patient values and preferences are important. Since patients report decisional conflict after deciding on participation in these trials, improving the decision making process is essential. We aim to develop and evaluate an Online Value Clarification Tool (OnVaCT) to assist patients in clarifying their values around this end-of-life decision. This improved sharing of values is hypothesized to support medical oncologists in tailoring their information to individual patients' needs and, consequently, to support patients in taking decisions in line with their values and reduce decisional conflict. METHODS: In the first part, patients' values and preferences and medical oncologists' views hereupon will be explored in interviews and focus groups to build a first prototype OnVaCT using digital communication (serious gaming). Next, we will test feasibility during think aloud sessions, to deliver a ready-to-implement OnVaCT. In the second part, the OnVaCT, with accompanied training module, will be evaluated in a pre-test (12-18 months before implementation) post-test (12-18 months after implementation) study in three major Dutch cancer centres. We will include 276 patients (> 18 years) with advanced cancer for whom standard systemic therapy is no longer available, and who are referred for participation in early phase clinical trials. The first consultation will be recorded to analyse patient-physician communication regarding the discussion of patients' values and the decision making process. Three weeks afterwards, decisional conflict will be measured. DISCUSSION: This project aims to support the discussion of patient values when considering participation in early phase clinical trials. By including patients before their first appointment with the medical oncologist and recording that consultation, we are able to link decisional conflict to the decision making process, e.g. the communication during consultation. The study faces challenges such as timely including patients within the short period between referral and first consultation. Furthermore, with new treatments being developed rapidly, molecular stratification may affect the patient populations included in the pre-test and post-test periods. TRIAL REGISTRATION: Netherlands Trial Registry number: NTR7551 (prospective; July 17, 2018).

Development and feasibility of a web application to monitor patients' cancer-related pain.

BACKGROUND: In the outpatient setting, pain management is often inadequate in patients with cancer-related pain, because of patient- and professional-related barriers in communication and infrequent contacts. The internet may provide new opportunities for monitoring these patients. PURPOSE: The purpose of this study was to investigate whether internet monitoring of cancer-related pain in outpatients was feasible. METHODS: We developed an internet application that contained a pain diary, eConsult, and patient pain education. In the pain diary, patients scored their pain intensity (0-10 Numeric Rating Scale) and analgesic use daily and their side effects twice a week. Feasibility was defined as the percentage of diaries patients completed during the first 6 weeks. RESULTS: We included 100 outpatients. Sixteen were not evaluable due to cognitive problems (2); withdrawal of participation (2); internet problems (2), or because they were too ill (10). During the first 6 weeks, 60% of 84 evaluable patients completed their diary for at least 65% of the days (median number of diaries, 21; range, 3-42) and asked for a median of five eConsults (range, 0-37). Patients most frequently used an eConsult for questions about pain or side effects, how to use their analgesics and to improve their self-management. Over the 6-week period, current pain intensity decreased from 3.3 (SD = 2) to 2.5 (SD = 1.6, p = 0.005), and worst pain intensity decreased from 5.7 (SD = 2) to 3.8 (SD = 2.0, p < 0.001). CONCLUSION: Internet monitoring of pain is feasible in most outpatients with cancer-related pain. The frequent use of the pain diary in the majority of patients indicates that those patients felt confident with the regular assessment of pain.

Scopolaminebutyl given prophylactically for death rattle: study protocol of a randomized double-blind placebo-controlled trial in a frail patient population (the SILENCE study).

BACKGROUND: Death rattle (DR), caused by mucus in the respiratory tract, occurs in about half of patients who are in the dying phase. Relatives often experience DR as distressing. Anticholinergics are recommended to treat DR, although there is no evidence for the effect of these drugs. Anticholinergic drugs decrease the production of mucus but do not affect existing mucus. We therefore hypothesize that these drugs are more effective when given prophylactically. METHODS: We set up a randomized double-blind, placebo-controlled, multi-center study evaluating the efficacy of prophylactically given subcutaneous scopolaminebutyl for the prevention of DR in the dying phase. The primary outcome is the occurrence of DR defined as grade ≥ 2 according to the scale of Back measured by a nurse at 2 consecutive time points with an interval of 4 h. Secondary outcomes include adverse effects, quality of dying, quality of life in the last three days and bereavement. A sub-study will explore the experience of participating in a clinical trial in the dying phase from the perspective of relatives. Four hospices will include 200 patients. DISCUSSION: This is the first double-blind placebo-controlled study to prevent DR in patients in the hospice setting. Research in dying patients is challenging. We will apply ethical and organizational strategies as suggested in the literature. TRIAL REGISTRATION: The trial is retrospectively registered in the Dutch Trial register, identifier NTR 6438 June 2017. EudractCT number 2016-002287-14.

Neutrophil Recovery in Breast Cancer Patients Receiving Docetaxel-Containing Chemotherapy with and without Granulocyte Colony-Stimulating Factor Prophylaxis.

OBJECTIVE: The primary outcome of the current study is, whether there is a protective effect of prior chemotherapy or of prior granulocyte colony-stimulating factor (G-CSF) on the next cycle blood cell counts. METHODS: Hematologic toxicity was evaluated, based on a randomized phase III study in breast cancer patients (n = 167) with >20% risk of febrile neutropenia. The primary endpoint was the nadir blood cell counts for patients treated with G-CSF given during all 6 chemotherapy cycles or limited to the first 2 chemotherapy cycles only. RESULTS: For the present analyses, 47 patients were eligible. In the G-CSF 1-6 arm, the median white blood cell count (WBC) and absolute neutrophil count (ANC) nadir slowly decreased from 10.8 × 109/L in cycle 1 to 7.5 × 109/L in cycle 6 and from 7.1 × 109/L to 5.5 × 109/L, respectively. The median WBC nadir in the G-CSF 1-2 arm decreased from 1.2 × 109/L in cycle 3 to 0.9 × 109/L in cycle 6 and the ANC nadir showed a grade 4 neutropenia of 0.1 × 109/L in cycles 3-6. All patients had ANC recovery to normal levels (≥1.5 × 109/L) without delay on day 1 of the next cycle. CONCLUSION: We conclude that there is no protective effect of prior G-CSF or prior chemotherapy use on nadir blood cell counts in subsequent cycles.

A review of factors explaining variability in fentanyl pharmacokinetics; focus on implications for cancer patients.

Fentanyl is a strong opioid that is available for various administration routes, and which is widely used to treat cancer-related pain. Many factors influence the fentanyl pharmacokinetics leading to a wide inter- and intrapatient variability. This systematic review summarizes multiple studied factors that potentially influence fentanyl pharmacokinetics with a focus on implications for cancer patients. The use of CYP3A4 inhibitors and inducers, impaired liver function, and heating of the patch potentially influence fentanyl pharmacokinetics in a clinically relevant way. In elderly patients, current data suggest that we should carefully dose fentanyl due to alterations in absorption and metabolism. The influence of BMI and gender on fentanyl pharmacokinetics is questionable, most probably due to a large heterogeneity in the published studies. Pharmacogenetics, e.g. the CYP3A5*3 gene polymorphism, may influence fentanyl pharmacokinetics as well, although further study is warranted. Several other factors have been studied but did not show significant and clinically relevant effects on fentanyl pharmacokinetics. Unfortunately, most of the published papers that studied factors influencing fentanyl pharmacokinetics describe healthy volunteers instead of cancer patients. Results from the studies in volunteers may not be simply extrapolated to cancer patients because of multiple confounding factors. To handle fentanyl treatment in a population of cancer patients, it is essential that physicians recognize factors that influence fentanyl pharmacokinetics, thereby preventing potential side-effects and increasing its efficacy.

Feasibility of assessing patients' acceptable pain in a randomized controlled trial on a patient pain education program.

BACKGROUND: For patients with cancer-related pain, the numeric rating scale is the most frequently used instrument to measure pain intensity. In the literature, it has been suggested to interpret patient-reported ratings of pain in relation to the pain intensity which is acceptable to the individual patient. AIM: We aimed to examine the feasibility and course of acceptable pain intensity. DESIGN: A secondary analysis of a randomized controlled trial that tested the effectiveness of standard care versus standard care supplemented by a pain consultation combined with a patient pain education program. SETTING: A total of 72 patients were included from an outpatient oncology clinic of a university hospital. They were diagnosed with cancer-related nociceptive pain with an average pain intensity ⩾4. RESULTS: Most patients (97%) were able to give a score for acceptable pain. Almost half of the patients scored their acceptable pain in the range of moderate to severe. Patients' ratings of acceptable pain were stable; after 8 weeks, 69% of patients had a variation of up to 1 point compared to baseline. However, the mean acceptable pain intensity remained equal in the standard care group (from 4.6 (range: 0-8) to 5.0 (range: 2-8)) and decreased in the intervention group (from 4.6 (range: 2-8) to 3.8 (range: 0-7, p < 0.01), difference between groups p < 0.05). CONCLUSION: Measurement of acceptable pain intensity is feasible. Patients with additional pain treatment became more critical and accepted less pain. More research is needed before we can use acceptable pain intensity as a reference for the interpretation of pain ratings.
